Curtis s is going to the store to buy candy. Bags of candy corn cost $3 and bags of mini candy bars cost $5. He needs to buy at least 20 bags of candy and he cannot spend more than $75. Write a system of linear inequalities to model the situation and then solve by graphing. (Insert a picture of your graph done by hand)

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
